Your goal during this activity is to design an experiment to determine the effect of a single independent variable (either pH or temperature) on the activity of catalase enzyme. Watch the video below and explore the things you can vary, and what you can measure. Use the tools button in the upper right hand corner of the screen and the menu bar along the bottom of the video. What tools are available for you to measure with? What possible pH values can be used during the experiment? At which temperatures can the experiment be performed?.

Homo heidelbergensis was a tall, muscular hunter, who used both tools and weapons. because h. heidelbergensis was not a gatherer/forager, but ate a varied diet including meat and fish, we would expect to see what anatomical changes?

Hey everybody, i have another biology question. by what reproductive mechanism does a haplontic animal grow? initially mitosis, then meiosis completely by mitosis completely by meiosis initially by meiosis, then by mitosis

Scientists studied reproduction in the new zealand mud snail to answer the question, “are there benefits to reproducing sexually or asexually? ” which of these hypotheses would least likely aid the scientists as they worked to answer the question? sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation. asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring. sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation. asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social
